The Kinetis L family of devices all include a 48MHz ARM Cortex-M0+ core with 12 or 16-bit analog-to-digital converters, 12-bit digital-to-analog converters, high-speed analog comparators and low-power touch sensing with wake-up on touch from reduced power states.
“In our view, 8- and 16-bit development has reached the end of the road. Those architectures simply can’t keep up as the Internet of Things gains traction,” said Geoff Lees, vice president and general manager of Freescale’s Industrial & Multi-Market MCU business. “Kinetis L series MCUs are ideal for the new wave of connected applications, combining the required energy efficiency, low price, development ease and small footprint with the enhanced performance, peripherals, enablement and scalability of the Kinetis 32bit portfolio.”
The first of three Kinetis L series families is the Kinetis L0 with up to 32KB of flash memory and ultra-small 4mm x 4mm QFN packages. This is pin compatible with the Freescale 8-bit S08P family and software- and tool-compatible with all other Kinetis L series families.
The Kinetis L1 family has 32 to 256 KB of flash memory and additional communications and analog peripheral options, while the Kinetis L2 adds USB 2.0 full-speed host/device/OTG. These L series devices are pin- and software-compatible with the Kinetis K series, built on the ARM Cortex-M4 processor, providing a migration path to DSP performance and advanced feature integration.
As machine-to-machine communication expands and network connectivity becomes ubiquitous, many of today’s standalone, entry-level applications will require more intelligence and functionality. With the Kinetis L series, Freescale provides the ideal opportunity for users of legacy 8- and 16-bit architectures to migrate to 32-bit platforms and bring additional intelligence to everyday devices without increasing power consumption and cost or sacrificing space. Applications, such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control, can now leverage 32-bit capabilities and the scalability needed to expand future product lines – all at 8- and 16-bit
